Valavu ya BS1873 padziko lonse lapansi

Ndi imodzi mwa mapangidwe otchuka kwambiri a ma globe valves, a US ndi API system. M'mimba mwake, zipangizo, maso ndi maso, makulidwe a khoma, kutentha kwa kuthamanga, zimatanthauzidwa ndi ASME B16.34.

aValavu ya BS1873 padziko lonse lapansiingagwiritsidwenso ntchito poyendetsa. Ma valve ambiri okhala ndi malo amodzi amagwiritsa ntchito kapangidwe ka khola kapena kosungira kuti asunge mphete ya mpando, kupereka chitsogozo cha pulagi ya valve, komanso kupereka njira yokhazikitsira makhalidwe enaake a valavu. Itha kusinthidwa mosavuta posintha magawo odulira kuti asinthe mawonekedwe a flow kapena kupereka mphamvu yochepa.kuyenda, kuchepetsa phokoso, kapena kuchepetsa kapena kuchotsa cavitation.

Mapangidwe a Thupi la ASME Globe Valve, pali mapangidwe atatu akuluakulu a thupi kapena mapangidwe a ma valve a Globe, omwe ndi:

1). Chitsanzo Chokhazikika (chomwe chimadziwikanso kuti Chitsanzo cha Tee kapena T - Chitsanzo kapena Z - Chitsanzo)
2). Chitsanzo cha ngodya
3). Kapangidwe ka Oblique (komwe kumadziwikanso kuti Kapangidwe ka Wye kapena Kapangidwe ka Y)

Mfundo Yogwirira Ntchito yaValavu ya BS1873 padziko lonse lapansi

Valavu yozungulira imakhala ndi diski yosunthika ndi mpando wozungulira wosasuntha m'thupi lozungulira. Mpando wa valavu yozungulira uli pakati ndipo umagwirizana ndi chitoliro, ndipo malo otseguka pampandowo amatsekedwa ndi diskiyo. Pamene gudumu lamanja likuzunguliridwa ndi manja kapena ndi actuator, kuyenda kwa diski kumayendetsedwa (kutsitsidwa kapena kukwezedwa) pogwiritsa ntchito tsinde la valavu. Pamene diski yozungulira ya valavu ikukhala pamwamba pa mphete ya mpando, kuyenda kumayima kwathunthu.

Mbali yaikulu ya BS1873 globe valve

1) .Good kusindikiza mphamvu
2). Mtunda waufupi woyenda wa diski (sitiroko) pakati pa malo otseguka ndi otsekedwa,Ma valve a ASME padziko lonse lapansindi abwino ngati valavu iyenera kutsegulidwa ndi kutsekedwa pafupipafupi;
3).Vavu ya ASME globe ingagwiritsidwe ntchito ngati valavu yoyimitsa galimoto mwa kusintha kapangidwe kake pang'ono.
4).TApa pali maluso osiyanasiyana omwe amapezeka mu mitundu ya tee, Wye, ndi angle body.

Kugwiritsa ntchito BS1873 globe valve

Valavu ya BS1873 padziko lonse lapansiimagwiritsidwa ntchito kwambiri m'mautumiki osiyanasiyana; onse a kuthamanga pang'ono komanso kuthamanga kwambiri kwa madzi. Ma valve ozungulira ndi awa:

1). Yopangidwira mapaipi okhazikika pafupipafupi, kapena kupopera madzi ndi mpweya wapakati
2). Madzi: Madzi, nthunzi, mpweya, mafuta osaphika ndi zinthu zopangidwa ndi mafuta, mpweya wachilengedwe, mpweya wozizira, njira zamakono, mpweya, mpweya wamadzimadzi ndi wosakwiya
3).Mafuta ndi Gasi, Madzi Odyetsa, chakudya cha mankhwala, Malo Oyeretsera, makina otulutsira mpweya wa condenser, ndi makina otulutsira madzi.
4).Maboiler vents ndi drain, Utumiki wa nthunzi, ma drain akuluakulu a nthunzi ndi drain, ndi ma heater drain.
5).Turbine imatseka ndi kutulutsa madzi.
